> Upstream test result for windowing_windowspec2.q seems to return consistent
> result while we have observe that in a different test env, the result could
> be slightly different.
> e.g., for the following query, the value t could be the same in each
> partition of ts. So the row order could be either for those rows. I haven't
> looked further why it causes that difference yet.
> {noformat}
> select ts, f, max(f) over (partition by ts order by t rows between 2
> preceding and 1 preceding) from over10k limit 100;
> {noformat}
